Thanks for the suggestions. I don't want to spend much time and money on the wheels so will probably just clean them up and paint(brush or spray) with Rust-Oleum.
While rolling my sixth wheel and tire out of the garage I realized that they are getting heavier! I thought I, and the truck, were going to live for ever. I wonder if I could get the spare tire back up where it belongs next time I have to use it. Even when I was younger I had a hard time with that job.
Bought these tires ten years ago. Lots of tread left and no cracks but getting old. Fortunately I carry very little weight in the truck.
Thanks again for the help. Dale
